  • Applications

    Icosanal, CAS 2400-66-0, is primarily used as a fragrance ingredient and fixative in perfumery, cosmetics, and personal care formulations to enhance scent longevity and profile; it also serves as a chemical intermediate for the synthesis of fragrant esters used in fragrance applications; additional applications include household and cleaning products (air fresheners, fabric softeners, detergents) as an odorant-bearing component; in industrial settings it can function as a chemical intermediate for the synthesis of aromatic compounds and may be employed in coatings or inks as a scent additive; use is subject to local regulations and formulation limits.
